APPARATUS FOR APPLYIN ARMATURE-BANDS.

Specification of Letters Patent.

Patented Aug. 4, 1908.

Application filed. June 27, 1907. Serial No. 381,121.

To all whom it may concern:

Be it known that I, ROBERT E. MANLEY, of Hanover, in the county of York and State of Pennsylvania. have invented a certain new and useful Improvement in Ap aratus for Applying Armature-Bands; an( I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to apparatus for facilitating the application ofretaining bands on electric motor and enerator armatures and the formation of field coils for'such motors and generators, the objects of the invention being to provide a simple mechanism adapted for handling armatures or coils of any size within wide limits and which shall be under absolute control of the workman while leaving his hands free to solder, adjust or bind the strands forming the bands or coils.

' end of Fig. 1.

Other objects of the invention are to provide an a )paratns with which the tension on the strands may be maintained when the retation of the armature or coil is arrested and in which the slack in the driving connections shall be automatically taken up.

The invention consists in certain novel details of construction and combinations and arrangements of parts all as will be now described and pointed out particularly in the ap )ended claims.

' n the accompanying drawings: Figure l is a front elevation of an apparatus embodying the )resent improvements with an armature and field coil form shown in dotted lines. Fig. 2 is an elevation looking at the left hand Fig. 3 is a detail front elevation showing a coil form. Fig. -i is a view showing a coil form in side elevation. Fig. 5 is a detail elevation of the large shaft clampin s irockct wheel- I Li e letters of reference in the several figures indicate the same parts.

The frame A. of the apparatus is preferably in the form of a relatively light but strong stand well braced and having a substantially horizontal bed or top A on which are. mounted the standards B, B, for sup )orting the armature or coil shaft. The standard 13 may be mounted in fixed position at one end of the bed, while the standard B is adjnstably mounted on the bed by clamps or hand wheels b, shown in dotted lines, Fi 1.

A drive shaft C is journaled in the lower portion of the stand and provided with fast and loose belt ulleys C C to which power may be applied from a ower -shaft in an convenient location. X belt shifter mounted to slide on a square or s lined shaft or uide E serves to shift the be t from one pulley to the other, said .belt shifter being moved to shift the belt tothe fast- )ulley by a spring D and connected through a rod or siaft D with a bellcrank foot lever 01'."

A catch F is provided for holding the V treadle down, and as a convenient form consists of a fingerf projecting from a base secured to the floor and adapted to engage in an opening in the treadle when the latter is pressed down and laterally beneath the finger and to readily release the t-readle when the latter is pressed down and laterally from beneath the finger.

In order to control the drive shaft and the parts driven thereby to be presentl described, the shaft is rovided with a lirake drum G on which a riction brake G rests, said brake being connected through a rod 9 with the treadle. A nut or enlargement g on the rod serves to lift the brake when the treadle rises and aspring g on the rod above the brake insures the ap lication of the brake before the belt has been completely shifted and at the same time permits the treadle to continue its movement to completely shift the belt and engage the catch. The drive shaft is also provided with pinions or small gear wheels H preferably of different size and one or the other of which is adapted to engage with one or the other of a palr of change gears H either of which may be placed on a counter shaft I journaled in the stand. On its outer end the counter shaft carries as rocket wheel K for a drive chain K, said c iain also passing around a larger sprocket wheel L preferably mormted directly on the shaft carrying the armature or coil form.

To permit of the sprocketivheel being readily applied to the shaft and held rigidly in' centered position thereon without injury to the shaft, the wheel is provided wit-h radially movable brass centering and clamping jaws .5 L sai applied as will be readily understood.

The armature shaftor shaft carrying the coil form is adapted to rest on the top of the standards B, B, each of the latter being provided with brass anti-friction wheels on and between which the shaft rotates.

The anti-friction wheels may all be adjustably mounted in the standards to facilitate adjustment and to accommodate shafts of different size, but in practice it is found suflicient to mount the forward wheels .\I in fixed bearings and the rear wheels M in movable bearings M adjustable toward and from the forward wheels by set screws M By spacing the rolleis properly, it will be seen that not only can shafts of different size be accommodated, but shafts having different diameters at opposite ends may be alincd properly, and, further, by dropping the shaft wcl down between the rollers the necessit of providing top rollers to prevent the sha t riding out of its bearings is avoided.

' -As a precaution against the shaft being drawn oil' of the to of the standards should sudden strain on tie wire occur, the bearings of the front rollers may be extended above the rollers in the form of stops 0 against which the shaft will strike should an accident such as above contemplated occur. The tension of the sprocket chain is main- 40 tained by a gravity or spring pressed idler P,

preferab y mounted on'an arm P pivoted to a. su port P adjustably mounted on the end oft 1e stand, thus the chain will automatically accommodate itself to the sprocket wheels even though the axis of the upper sprocket wheel 18 high or low within reasonle limits and su'llicient slack may be allowed to permit of the removal of the chain when a new shaft or armature is to be put in position.

The wire is preferably led in over guide rollers Q journaied on a sleeve Q threaded on a shaft Q mounted in adjustable supports Q, carried by forwardly extending arms Q on the standards B B.

beparatc guide rollers may be emplo ed for the band and field coil wires but each is controlled in its position longitudinally of the shaft by a hand wheel Q, as it is preferred that the feed of the wire axially of the shaft should be under the direct and recise control of the workman.

lVhen fie d coils are to be wound, itis preferred that the form should be mounted on the free end of the shaft outside of the adjustable standard, as shown in dotted lines embodying a mem in Fig. 1 and in Figs. 3 and 4. The shaft in this instance may be held down intermediate the standards by a removable bearing Radjustably connected b r a'rod R with an anchor R under the bed of the machine.

The field coil form )referablyembodies two oppositely arranged ace plates S each slotted rat ially for the passage of binding tapes.v The face plates are adapted to clamp be tween them a core of any proper configuration corres )onding to the core of the field coil and are held together by clamping bolts s so as to be readily separated for the removal of the formed coil'or for the removal or insertion of anew core. A

In making use of the apparatus the workman has complete control through the treadle,

thus he can start and rotate the shaft a fraction of a revolution if he so desires and instantly stop and hold the shaft in its new position by the brake, even though the tension on the wire be very great. Both hands are free to solder or manipulate the wire as it is applied and the screw shaft Q affords a. convenient rest, the height of which may be adjusted, for the workman to rest his arms on in the more particular and careful steps of the operation.

In winding field coils the binding tapes are first passed through the slots in the face plates, then the wire is wound on, then the tapes are passed through the slots over the outside of the coil and made fast to )reserve the shape of the coil when removed rom the form.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:
